We describe a case of perioperative Addisonian crisis induced by vertebral augmentation. While several complications of vertebral augmentation have been reported previously, related to the technical procedure, to our knowledge, perioperative Addisonian crisis from vertebral augmentation has not been reported in the literature. ⋯ Addisonian crisis may be triggered by vertebral augmentation. Practitioners need to recognize immediately this potentially lethal disorder in patients with known or suspected adrenal insufficiency and treat with intravenous hydrocortisone.

Randomized Controlled Trial Comparative Study Clinical Trial
Topiramate in treatment of patients with chronic low back pain: a randomized, double-blind, placebo-controlled study.
Chronic low back pain (CLBP) is a widespread ailment. The aim of this study was to assess the efficacy of topiramate in the treatment of CLBP and the changes in anger status and processing, body weight, subjective pain-related disability and health-related quality of life during the course of treatment. ⋯ Topiramate seems to be a relatively safe and effective agent in the treatment of CLBP. Significantly positive changes in pain sensitivity, anger status and processing, subjective disability, health-related quality of life, and loss of weight were observed.

Cognitive-behavioral factors are considered important in the development of chronic disability and pain in patients with low back pain. In a prospective cohort study of 277 patients undergoing surgery for lumbosacral radicular syndrome, the predictive value of preoperatively measured cognitive-behavioral factors (fear of movement/(re)injury, passive pain coping, and negative outcome expectancies) for disability and pain intensity at 6 weeks and 6 months after surgery was investigated, taking into account the effect of possible confounding variables. Higher levels of cognitive-behavioral factors were found to be associated with a worse outcome at both 6 weeks and 6 months. ⋯ In multiple regression analyses, the cognitive-behavioral factors independently predicted different outcomes. Fear of movement/(re)injury predicted more disability and more severe pain at 6 weeks and more severe pain at 6 months; passive pain-coping strategies predicted more disability at 6 months; and negative outcome expectancies predicted more disability and more severe pain at both 6 weeks and 6 months. The findings support the potential utility of preoperative screening measures that include cognitive-behavioral factors for predicting surgical outcome, as well as studies to examine the potential benefits of cognitive-behavioral treatment to improve surgical outcome.

Randomized Controlled Trial Comparative Study
Comparison of a biopsychosocial therapy (BT) with a conventional biomedical therapy (MT) of subacute low back pain in the first episode of sick leave: a randomized controlled trial.
This randomized controlled clinical trial compares the effectiveness of a biopsychosocial treatment with a solely conventional biomedical therapy in patients with subacute low back pain using parameters for pain intensity, functional status, depressive dysfunction and work performance. Sixty-four patients with a first-time sick leave between 3 and 12 weeks due to low back pain were randomly assigned to either a conventional biomedical therapy (MT; n=33) group, or a biopsychosocial therapy (BT; n=31) group including a psychotherapeutic module; both in accordance with a standardized 3 weeks inpatient treatment. ⋯ During the 2-year period after therapy, 10% in MT and 59% in BT required no further sick leave due to low back pain. The results of the study indicate that a psychotherapeutic element in the treatment of low back pain appears to positively influence pain, functional status and work performance when conducted at an early stage of chronification and helps in the achievement of a better outcome.

Only controlled intra-articular zygapophyseal joint (ZJ) injections or medial branch blocks can diagnose ZJ-mediated low back pain. The low prevalence of ZJ pain implies that identification of clinical predictors of a positive response to a screening block is needed. ⋯ A negative extension rotation test, the centralization phenomenon, and four CPRs effectively rule out pain ablation after screening ZJ block. One CPR generates a fivefold improvement in posttest probability of a negative or positive response to ZJ block.
